All about your sewer camera inspection

A camera inspection of sewer pipes is an accurate method to map the condition of the sewer without digging or demolition work. With the help of special sewer cameras, the inside of pipes is inspected for cracks, blockages, root growth, subsidence and other defects.
This technique is used both for preventive maintenance and for tracing the cause of recurring blockages or odor complaints, and is suitable for both private homes and large utility buildings.

1. Goals of a camera inspection

• Visually recording the condition of the pipes.
• Detecting defects such as cracks, fractures, leaks and root growth.
• Determining the exact location of the problem for targeted repair.
• Preventing unnecessary digging and hacking.

2. Operation of the inspection technique

A camera inspection uses:

• Push cameras for pipes with a smaller diameter.
• Driving camera units (crawler cameras) for larger sewer pipes.
• 360° rotating lenses for a complete picture of the tube wall.
• Location transmitters to determine the exact location of a defect.
• HD or 4K video recordings for accurate reporting.

The camera is inserted into the pipe via an access point, such as an inspection pit or cleanout. As the camera moves through the pipe, images and measurements are recorded live.

3. Common findings

• Cracks and fractures in the piping.
• Root growth from surrounding vegetation.
• Blockages due to grease, dirt, construction waste or subsidence.
• Leaks at joints or couplings.
• Connection errors or incorrect slope of pipes.
• Corrosion or wear in old metal pipes.

4. Application moments

• Recurring blockages of unknown cause.
• Preventive check for older pipes or after ground work.
• Inspection upon purchase or sale of a property.
• Check after repair to verify repair.
• Investigation in case of odor nuisance.

5. Legal and normative frameworks

Although camera inspections are not legally mandatory themselves, in many cases reference is made to standards and guidelines such as:

• NEN 3399 – classification of sewer deviations.
• NEN-EN 13508-2 – inspection procedures and reporting methods.
• Building Decree 2012 – requirements for drainage and sewerage systems.

6. Benefits of camera inspection

• No unnecessary digging.
• Fast and accurate diagnosis.
• Complete visual reporting for repair planning.
• Cost-effective due to targeted repair.
• Ideal for both emergencies and preventive maintenance.
